Watch the 2 millionth Cummins engine for the Ram being built

Of course because the Cummins only has 6 connecting rods while the other 2 have 8! On top of that, your mighty Cummins you speak of is always the last in performance so what good does those 6 larger connecting rods do? Hold it back and using the most fuel per mile trying to move the extra un-needed weight? The other 2 have not had any issues with their "smaller" sized eight connecting rods!
